About Lookup Manager Component

The Lookup Manager component determines the correct recipients for faxes sent to DID/DTMF extensions. This component uses Windows 2000 Active Directories to find matches in the recipient's record (in the Fax field on the Phone/Notes tab) in the Microsoft Exchange Server Administrator.

The Lookup Manager component can route faxes to multiple users that all share the same extension number. For example, if one DID extension is assigned to five users, the Lookup Manager component routes all faxes destined for that DID extension to all five users.

Tip: Each connector that uses Lookup can use a different Lookup server and search criteria. You can configure these properties in the specific connector's properties.

You can have up to four instances of this component. You should not modify its settings unless Technical Support instructs you to do so.

An LDAP filter defines the criteria of a search. You can customize the filter that is used to search for DID/DTMF recipients on inbound faxes. You can customize the filter for each connector that you have configured to use Lookup.

Customization may be required if fax numbers are stored in your database in a format instead of just as a string of numbers (for example, formatted as (603) 898-8900 instead of 6038988900). You can use a custom filter to format the received fax number into the format that the Lookup Manager needs to match in the LDAP database.

You can use two methods to customize filters.

Simple Filter

  • The first option is the simple filter, where you choose options from a list.

Custom Filter

  • The second option is the custom filter, where you can create a filter by hand. Custom filters are intended for use by advanced LDAP users. The advanced custom filter option requires you to design the filter using a standard LDAP syntax. An overview of the expected syntax is provided below, but it is not intended to explain how to build a filter.
  • For more in depth information, consult your LDAP administrator or any documentation you may have available on the subject.

When creating a custom filter for DID/DTMF Lookup, use the following syntax and guidelines.

  • Use Prefix Notation

  • Use pound signs (#) to represent a single digit

  • Use a percent sign (%) to represent the entire captured DID/DTMF extension

  • Use asterisks (*) to represent wildcards in the search

  • Pound signs (#) are replaced from right to left. For example:

So, if the filter states: facsimileTelephoneNumber=*##-#### and the captured DID is: 6038988900, the search will match using this pattern: *98-8900.

The reason is because the captured DID replaces the symbols in the filter from right to left, so the filter captured only the last 6 digits of the DID number. The seventh is the wildcard, so the filter will match any number in the database that ends in 98-8900.

The format you use in your filter must match the format of fax numbers stored in your database. For example, if fax numbers are entered as 603-898-8900, use ###-###-#### as the format in your filter.
